Publisher's Announcement 



The writer has been publishing ' ' Smith 's Com- 
puter" for nine years and its popularity has in- 
creased steadily each year. During these years 
the business of cream buying has grown wonder- 
fully. In almost every town, in most of the 
states, where there is no creamery, there are from 
two to four cream buyers for the large central 
creameries. These men usually buy cream, milk, 
butter, eggs and poiiltry. ]\Iany letters have 
come to the publisher of this computer asking if 
he had a small, compact set of tables at a small 
cost that would cover the needs of the creamery 
and the country "Cream Buyers." 

In response to these inquiries and suggestions 
"Smith's Butterfat Computer" has been publish- 
ed. The tables have been arranged in handy 
form, to meet every need of these busy men. The 
type is large and the tables are very simple and 
easily applied and when once used will prove a 
boon to the creameryman or the buyer of cream, 
milk, eggs, butter and butterfat. 

My faith in the correctness of every figure in 
this book is so strong that I will send a copy free 
to the first person reporting an error in the tables. 
If you find an error report at once. 

Hoping this computer will find a warm re- 
ception by those for whom it is intended, 

I am respectfully, 

J.. FRANK SMITH, Publisher, 

May, 1915. Pleasanton, Kansas. 



HOW TO APPLY THE TABLES. 

The success of the tables in this computer depends 
on the operator, and to get quick results, one should 
know how to apply them to the best advantage. The 
tables are simple and easy to understand and are capa- 
ble of a wide range of application. Here are a few 
rules and suggestions that will enable one not familiar 
with them to apply the tables. 

TO FIND BUTTERFAT IN CREAM. 

The tables have a wide range for tests of cream 
including all tests from 15% to 70% with the half frac- 
tion in each table. To find the fat in any lot of cream 
use the table representing the test and run to the num 
ber representing the number of pounds and the num- 
ber opposite is the pounds of fat. Example: 25 lbs 
cream test 27%. Use the 27 table and run to 25 and 
you have 6.75 lbs. fat. 

TO FIND PAT IN WHOLE MILK. 

The tables include the tests of whole milk from 
1.5%. to 1% with all the tenths. To get the fat In any 
lot of milk, use the table representing the test and run 
to ihe number of pounds. Example, 75 lbs. milk test 
3.4%. Use the 34 table and run to 76 and you have 
25.84, but since the test is 3.4%> In place of 34% the 
decimal should be moved one place to the left and it 
leaves 2.58 lbs. fat. 



TO FIND VALUE OF FAT AT ANY PRICE. 

The tables may be transposed any way and the 
correct results obtained. Example, 34 lbs. fat at 25 
cts. per lb. Use the 34 table and run to 25, or use the 
25 table and run to 34. Another example, 34 1-2 lbs. 
fat at 25 cts. per lb. Use the 34 1-2 table and run to 
25. Example, 34 lbs. fat at 25 1-2 cts. per lb. Use the 
25 1-2 table and run to 34. Example, 9.8 lbs. fat at 25 
cts. per lb. Use the 25 table and run to 98 and move 
the decimal one place to the left. Example, 45.8 lbs. 
fat at 25 1-2 cts. per lb. Use the 25 1-2 table and run 
to 45 and you have the value of the 45 lbs. Then run 
to 8 and move the decimal one place to the left and 
add to value of 45 lbs. 

TO FIND VALUE OF BUTTER. 

Apply the tables the same as in butterfat. 

TO FIND FAT IN MORE THAN 100 LBS. OP 
CREAM OR MILK. 

Since the tables only run to 100 it is well to knov/ 
how to compute the fat in more than 100 lbs. of cream 
or milk. To compute fat in 450 lbs. cream or milk, 
use the table representing the test and run to 45 and 
to the result add one cipher and move decimal one 
place to right. To compute fat in 567 lbs. milk or fat, 
use table giving test and run to 5 and add two ciphers 
and move decimal two places to right. Then compute 
67 and add. If it is 6578 lbs. milk test 4.5%. First 
use the 45 table and run to 65 and move the decimal 
one place to right. Then run to 78 and move the deci- 
mal one place to left and add the two. By carefully 
studying this system and learning to shift the decimal 
point correctly one can compute cream and milk up to 
several thousand pounds with only one addition. 

TO FIND VALUE OF EGGS. 

Use the table representing the price of eggs and 
run to the number representing the number of dozen. 
The result will be the value. If you have parts of a 
dozen it is necessary to learn the decimal to represent 
the odd number of eggs to get the exact value. Here 
is a table that will enable one to compute value of 
eggs in broken lots: 1, (1-12 doz.) equals .08; 2, (1-6 
doz.) ea.uals .17; 3, (1-4 doz.) equals .25; 4, (1-3 doz.) 
equals .33; 5, (5-12 doz.) equals .42; 6, (1-2 doz.) equals 
.50; 7, (7-12 doz.) equals .58; 8, (2-3 doz.) equals .67; 
9, (3-4 doz.) equals .75; 10, (5-6 doz.) equals .83; 11, 
(11-12 doz.) equals .92. Example, 13 doz. and 7 eggs 
at 23 cts. per doz. Use the 23 table and run to 13 and 
you have $2.99 and to get the value of 7 eggs run to 
58 and you have 13 cts. This is easy and correct and 
when once used will be very handy. 

TO FIND VALUE OF POULTRY. 

Apply the tables the same as in finding value of 
butter or butterfat. 

EACH TABLE MAY REPRESENT SEVERAL 
NUMBERS. 

Each table in the computer can be used to repre- 
sent five or more numbers very easily. Example, 22 1-2 
table can represent milk test of 2.25% or cream test 
22 1-2";^ or value of butter or butterfat at 22 1-2 cts. per 
lb., or any articles at $2.25 each or per pound, and also 
$22.50 per each or dozen or any other way. The varied 
number of uses to which the tables may be applied de- 
pends on the operator and his ability to shift the deci- 
mal point. With a little study there is hardly any 
limit to their application. 

If a user of the computer has any difficulty in ap- 
plying the tables, after reading the instructions, he is 
invited to write to the publisher, telling his troubles 
and enclosing a few examples. A reply will follow at 
once and a special effort made to explain the particular 
application of the tables.

Here Is a rule to compute value ot less thau dozeu eggs at 
any price. 1 egg, (1-12 doz.) equals .OS of a dozen ; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz) equals .25; 4, (1-3) equals 
.33; 5, (5-12) equals .42; 6, (1-2) equals .50; 7, (7-12) equals 
.58; 8, (2-3) equals .07; 0, (3-4) equals .75; 10, (5-6) equals .83; 
11, (11-12) equals .92. tJuder the table representing tlie price 
per dozen of eggs, use these numbers as decimals and you 
will always get correct value ot odd eggs.

Here is a rule to compute Talue ot less tli.in dozeu eggs at 
any rrice. 1 egg, (1-12 doz.) equals .OS of a dozen; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .23; 4, (1-3) equals 
.33; 5, (5-12) equals .42; 6, (1-2) equals .50; 7, (7-12) equals 
.58; 8, (2-3) equals .07; 9, (3-4) equals .75; 10, (5-G) equals .83; 
11, (11-12) equals .92. Under tlio table representing tlie price 
per dozeu of eggs, use tUese numbers as decimals and you 
will always get correct value of odd eggs.

Here Is a rule to compute value of less tbau dozen esss at 
any price. 1 ess. (1-12 doz.) equals .OS of a dozen; 2 eggs, 
(1-6 doz.) equals .17; S, (1-4 doz.) equals .25; 4, (1-3) equals 
..13; 5, (5-12) equals .42; G, (1-2) equals .50; 7, (7-12) equals 
.58; 8, (2-3) equals .67; 9, (3-4) equals .75; 10, (5-6) equals .83; 
11, (11-12) equals .92. Uuder tlie table representiug the price 
per dozen of eggs, use tliese numbers as decimals and you 
will always get correct value of odd eggs.

Here is a rule to compute value of less than dozen eggs at 
any price. 1 egg, (1-12 doz.) equals .OS of a dozen ; 2 eggs, 
(1-6 doz.) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
.33; 5, (5-12) equals .42; fi. (1-2) equals .50; 7. (7-12) equals 
.58; 8, (2-3) equals .07; tl, (3-4) equals .75; 10, (5-«) equals .83; 
11. (11-12) equals .02. Under the table representing the price 
per dozen of eggs, use these numbers as decimals and you 
■will nl-rrnys get correct value of odd eggs.

Here is a rule to compute T.-ilue of less tban dozeu egss at 
any price. 1 egij, (1-12 doz.) equals .08 of a dozeu; 2 eggs, 
(1-C doz.) equals .17; 3, (1-4 doz.) equals .25; 4, (1-3) equals 
33; 5, (.")-12) equals .42; 6, (1-2) equals .50; 7. (7-12) equals 
58; 8, (2-3) equals .07; 9, (3-4) equals .75; 10, (5-6) equals .83; 
11 (11-12) equals .U2. Under the table representluj; tlie price 
per dozen of eggs, use these numbers as decimals and you 
will always get correct value of odd eggs.
